Abstract

En fremgangsmåte for bestemmelse av slamsenhet for et slam i et borehull inkluderer bestemmelse av senhet som en funksjon av frekvens for minst én fluidmodus fra et sett av målinger som er innsamlet med et sonisk verktøy (10, 20) i borehullet; og bestemmelse av slamsenheten fra senheten som en funksjon av frekvens for den minst ene fluidmodus. Et system for bestemmelse av slamsenhet for et slam i et borehull, omfattende en prosessor (91) og et minne (93), hvor minnet lagrer et program som har instruksjoner for bestemmelse av senhet som en funksjon av frekvens for minst én fluidmodus fra et sett av målinger som er innsamlet med et sonisk verktøy i borehullet; og bestemmelse av slamsenheten fra senheten som en funksjon av frekvens for den minst ene fluidmodus.A method of determining sludge unit for a sludge in a borehole includes determining unit as a function of frequency for at least one fluid mode from a set of measurements collected with a sonic tool (10, 20) in the borehole; and determining the sludge unit from the unit as a function of frequency for the at least one fluid mode. A system for determining sludge unit for a wellbore sludge, comprising a processor (91) and a memory (93), the memory storing a program having instructions for determining sludge as a function of frequency for at least one fluid mode from a set of measurements collected with a sonic tool in the borehole; and determining the sludge unit from the unit as a function of frequency for the at least one fluid mode.
